Description

Technical Field

[0001] This application relates to the field of geomembrane production technology, specifically a mixing device for geomembrane production. Background Technology

[0002] Geomembrane is a flexible, thin-film geosynthetic material made from high-molecular polymers through processes such as extrusion and calendering. It possesses seepage-proof and isolation functions and is often combined with substrates such as non-woven fabrics to form composite geomembranes. Widely used in water conservancy, municipal engineering, environmental protection, and transportation projects, it is a key material for ensuring the seepage prevention performance of engineering projects and improving structural stability. In the geomembrane production field, the mixing device is one of the core pieces of equipment that ensures the uniformity of raw material mixing, thus determining the performance of the finished geomembrane.

[0003] Chinese utility model patent CN218985327U discloses a high-efficiency mixing device for geomembrane production. It uses a diamond-shaped telescopic transmission sleeve in conjunction with a rotating sleeve to drive a damping spring, causing the mixing shaft and blades to oscillate horizontally and vertically while rotating, thus accelerating the mixing of raw materials in the mixing tank. However, during use, the raw materials are directly fed into the mixing tank through the feed pipe. Dust and fine impurities carried by the raw materials during transportation and storage will enter the mixing tank along with the raw materials and mix with other components. On the one hand, the inclusion of impurities affects the uniformity of the mixing; some impurities may even adhere to the surface of the mixing mechanism or the inner wall of the mixing tank, forming localized material agglomerations, reducing the mixing quality, and leading to uneven performance of the subsequently produced geomembrane. On the other hand, hard, fine impurities will experience rigid friction with the mixing mechanism during the mixing process, accelerating the wear of the mixing components and shortening the equipment's service life.

[0004] Therefore, this application provides a mixing device for geomembrane production to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a mixing device for geomembrane production, aiming to solve the problems mentioned in the background art, such as the method of directly feeding raw materials into the mixing tank through the feed pipe when using existing high-efficiency mixing devices for geomembrane production, which makes it easy for impurities carried in the raw materials to be mixed in, affecting the uniformity of raw material mixing and thus causing uneven performance of the finished geomembrane. In addition, the rigid friction between the carried hard impurities and the mixing mechanism will accelerate the wear of parts and shorten the service life of the equipment.

[0006] To achieve the above objectives, this application provides the following technical solution: a mixing device for geomembrane production, comprising a mixing tank, a feed pipe fixedly connected to one side of the top of the mixing tank, a discharge pipe fixedly connected to the bottom of the mixing tank, and a stirring mechanism disposed on the mixing tank for mixing the raw materials in the mixing tank. The mixing device further comprises a dust suction mechanism disposed on one side of the mixing tank and communicating with the feed pipe for removing dust and fine impurities from the raw materials when the feed pipe enters the raw materials.

[0007] The dust collection mechanism includes a dust collection pipe fixedly installed on one side of the feed pipe, an air pump installed on one side of the mixing tank and fixedly connected to the end of the dust collection pipe away from the feed pipe, and a conveying component installed on the end of the air pump away from the dust collection pipe for collecting dust and fine impurities.

[0008] A grid is fixedly installed at one end of the suction pipe near the feed pipe to prevent raw materials from entering the feed pipe. The suction mechanism, consisting of the suction pipe, air pump, and conveying components, is designed to remove dust and fine impurities from the raw materials when they enter the mixing tank through the feed pipe. This prevents impurities from entering the mixing tank with the raw materials and mixing with other materials. This not only improves the purity of the raw materials from the source to ensure the quality of the geomembrane product, but also prevents impurities from wearing down the mixing mechanism, thus extending the equipment's lifespan. At the same time, the grid design can prevent qualified raw materials from entering the suction pipe, only removing dust and fine impurities, ensuring the removal of impurities while avoiding material waste.

[0009] Preferably, in order to seal the feed pipe opening after the raw material is conveyed, a sealing cap for sealing the feed pipe opening is fastened to the feed pipe opening after the raw material is conveyed; the sealing cap and the feed pipe opening are fastened together to form a relatively closed space, thereby isolating the inside of the mixing tank from the external environment, thus preventing external dust, impurities, etc. from entering the mixing tank, ensuring the purity of the raw materials in the mixing tank, and avoiding affecting the quality of subsequent geomembrane production.

[0010] Preferably, in order to mix the raw materials in the mixing tank, the stirring mechanism includes a base fixedly installed at the center of the top of the mixing tank, a main shaft that runs longitudinally through the mixing tank and the base and is rotatably connected to the mixing tank and the base, a stirring rod fixedly connected to the main shaft and located inside the mixing tank, and a motor fixedly installed on the top of the base for driving the main shaft to rotate; the motor drives the main shaft to rotate, and the main shaft drives the stirring rod fixedly connected to it to rotate inside the mixing tank. The stirring rod can stir and mix the raw materials, thereby improving the uniformity of the raw material mixing and laying the foundation for the stable performance of the subsequent geomembrane product.

[0011] Preferably, in order to store and collect the dust and fine impurities sucked up by the vacuum pump, the conveying assembly includes a collection box disposed on one side of the vacuum pump for storing the collected dust and fine impurities, and a conveying pipe fixedly connected to the end of the vacuum pump away from the suction pipe. The end of the conveying pipe away from the vacuum pump is fixedly connected to the collection box. The combined design of the conveying pipe and the collection box allows dust and fine impurities to be sucked in through the suction pipe and then conveyed to the collection box for storage through the conveying pipe. This achieves effective collection and treatment of impurities, prevents secondary pollution from impurities, maintains the cleanliness of the production environment, and facilitates unified treatment of the collected impurities, thereby improving the environmental friendliness and management efficiency of the production process.

[0012] Preferably, to prevent clogging, the mixing device further includes an anti-clogging mechanism disposed inside the feed pipe and connected to the main shaft for scraping off the raw material adhering to the surface of the grid and agitating the raw material inside the feed pipe; the design of the anti-clogging mechanism can not only scrape off the raw material adhering to the surface of the grid to prevent the raw material from clogging the grid, but also agitate the raw material inside the feed pipe to avoid the accumulation of raw material inside the feed pipe, so as to ensure the stability of the feeding and dust collection process.

[0013] Preferably, in order to scrape off the raw material adhering to the grid surface and agitate the raw material in the feed pipe, the anti-clogging mechanism includes a fixed seat fixedly mounted on the base, a rotating shaft that runs horizontally through the feed pipe and the fixed seat and is rotatably connected to the feed pipe and the fixed seat, a scraper fixedly mounted on the rotating shaft and located inside the feed pipe for contacting the grid surface, a connecting bevel gear fixedly sleeved on the main shaft, and a transmission bevel gear fixedly sleeved on the end of the rotating shaft away from the scraper and meshing with the connecting bevel gear. Multiple scrapers are provided, and the multiple scrapers are arranged in a ring on the rotating shaft. Through the meshing action of the connecting bevel gear and the transmission bevel gear, when the main shaft rotates, it synchronously drives the rotating shaft and the multiple scrapers arranged in a ring on it to rotate. The scrapers, in contact with the grid surface, can scrape off the raw material adhering to the grid surface, and simultaneously agitate the raw material in the feed pipe, preventing material accumulation, thereby ensuring the normal operation of the dust collection mechanism and the smoothness of the feed.

[0014] The mixing device for geomembrane production is designed with a dust suction mechanism consisting of a dust suction pipe, an air pump, and a conveying component. When the raw material enters the mixing tank through the feed pipe, it can remove dust and fine impurities from the raw material, preventing impurities from entering the mixing tank with other raw materials. This not only improves the purity of the raw material from the source to ensure the quality of the finished geomembrane, but also prevents impurities from wearing down the mixing mechanism to extend the equipment's lifespan.

[0015] The mixing device for geomembrane production uses a grid design to prevent qualified raw materials from entering the dust suction pipe, only sucking away dust and fine impurities, thus ensuring the removal of impurities and avoiding waste of raw materials.

[0016] The mixing device for geomembrane production, through its anti-clogging mechanism design, can not only scrape off the raw materials adhering to the surface of the grid to prevent the raw materials from clogging the grid, but also stir the material inside the feed pipe to prevent the raw materials from accumulating inside the feed pipe, thus ensuring the stability of the feeding and dust collection process.

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Example 1

[0031] This embodiment provides a mixing device for geomembrane production, such as... Figures 1-4As shown, the mixing device includes a mixing tank 1, a feed pipe 2 fixedly connected to one side of the top of the mixing tank 1, a discharge pipe 3 fixedly connected to the bottom of the mixing tank 1, and a stirring mechanism 4 disposed on the mixing tank 1 for mixing the raw materials in the mixing tank 1. The mixing device also includes a dust suction mechanism 5 disposed on one side of the mixing tank 1 and connected to the feed pipe 2 for removing dust and fine impurities from the raw materials when the feed pipe 2 enters the raw materials. The dust suction mechanism 5 includes a dust suction pipe 51 fixedly disposed on one side of the feed pipe 2, an air pump 52 disposed on one side of the mixing tank 1 and fixedly connected to the end of the dust suction pipe 51 away from the feed pipe 2, and a conveying component 53 disposed on the end of the air pump 52 away from the dust suction pipe 51 for collecting dust and fine impurities. A grid 6 is fixedly installed on the end of the dust suction pipe 51 near the feed pipe 2 to prevent the raw materials from entering the feed pipe 2.

[0032] In use, the vacuum pump 52 and the mixing mechanism 4 in the dust collection mechanism 5 are started. First, the raw materials required for geomembrane production are added through the feed pipe 2. The raw materials are conveyed downward in the feed pipe 2 to enter the mixing tank 1. At this time, the vacuum pump 52 in the dust collection mechanism 5 is started, and the vacuum pump 52 generates negative pressure suction. The raw materials in the feed pipe 2 are adsorbed by negative pressure through the dust collection pipe 51 connected to the feed pipe 2. Dust and fine impurities mixed in the raw materials are sucked into the dust collection pipe 51 under the action of negative pressure. The grid 6 fixedly installed at one end of the dust collection pipe 51 near the feed pipe 2 will prevent qualified raw materials from entering the dust collection pipe 51. Only dust and fine impurities are allowed to enter the vacuum pump 52 through the suction pipe 51. The vacuum pump 52 then transports the sucked-in dust and fine impurities to the conveying component 53 connected to the end away from the suction pipe 51. The conveying component 53 collects the dust and fine impurities. After the raw material is conveyed and the impurities are removed, the qualified raw material enters the mixing tank 1. During this process, the raw material in the mixing tank 1 is stirred and mixed by the stirring mechanism 4. After the raw material is evenly mixed, the discharge pipe 3 at the bottom of the mixing tank 1 is opened to discharge the mixed raw material from the discharge pipe 3 for use in the subsequent geomembrane production process.

[0033] It should be noted that a valve is installed on the discharge pipe 3 for opening and closing.

[0034] In order to seal the opening of the feed pipe 2 after the raw material is conveyed, a sealing cover 21 is fastened to the opening of the feed pipe 2. The sealing cover 21 and the opening of the feed pipe 2 are fastened together to form a relatively closed space, thereby isolating the inside of the mixing tank 1 from the external environment, thus preventing external dust, impurities and other contaminants from entering the mixing tank 1, ensuring the purity of the raw materials in the mixing tank 1, and avoiding any impact on the quality of subsequent geomembrane production.

[0035] Specifically, the stirring mechanism 4 includes a base 41 fixedly installed at the center of the top of the mixing tank 1, a main shaft 42 that runs longitudinally through the mixing tank 1 and the base 41 and is rotatably connected to the mixing tank 1 and the base 41, a stirring rod 43 fixedly connected to the main shaft 42 and located inside the mixing tank 1, and a motor 44 fixedly installed on the top of the base 41 for driving the main shaft 42 to rotate.

[0036] When it is necessary to stir and mix the raw materials in the mixing tank 1, the motor 44, which is fixedly installed on the top of the base 41, is started first. The motor 44 outputs power to drive the main shaft 42 connected to it to rotate. The base 41 is fixedly installed at the center of the top of the mixing tank 1, providing stable installation support for the motor 44 and the main shaft 42. As the main shaft 42 rotates, the stirring rod 43, which is fixedly connected to the main shaft 42 and located in the mixing tank 1, rotates synchronously with the main shaft 42. The rotating stirring rod 43 contacts the raw materials in the mixing tank 1, stirring and turning the raw materials, so that the raw materials of different components can be mixed together, and finally the raw materials in the mixing tank 1 are uniformly mixed, providing uniformly mixed raw materials for subsequent geomembrane production.

[0037] Furthermore, the conveying assembly 53 includes a collection box 532 disposed on one side of the air pump 52 for storing the collected dust and fine impurities, and a conveying pipe 531 fixedly connected to the end of the air pump 52 away from the suction pipe 51, with the end of the conveying pipe 531 away from the air pump 52 fixedly connected to the collection box 532.

[0038] When the vacuum pump 52 is started and sucks out the dust and fine impurities in the raw material in the feed pipe 2, these dust and fine impurities will enter the conveying pipe 531, which is fixedly connected to the end of the vacuum pump 52 away from the dust suction pipe 51, with the airflow. The conveying pipe 531, as the conveying channel for airflow and impurities, will guide the dust and fine impurities to the collection box 532, which is fixedly connected to the end away from the vacuum pump 52. The dust and fine impurities entering the collection box 532 will be deposited in the box, achieving separation from the airflow. Finally, the collection and storage of dust and fine impurities are completed so that the impurities can be uniformly processed in the future, avoiding secondary pollution of the production environment by the impurities.

[0039] Example 2

[0040] Unlike Example 1, as Figures 2-4As shown, in order to prevent clogging, the mixing device also includes an anti-clogging mechanism 7, which is set inside the feed pipe 2 and connected to the main shaft 42 for scraping off the raw material adhering to the surface of the grid 6 and agitating the raw material in the feed pipe 2. The anti-clogging mechanism 7 includes a fixed seat 71 fixedly set on the base 41, a rotating shaft 72 that runs horizontally through the feed pipe 2 and the fixed seat 71 and is rotatably connected to the feed pipe 2 and the fixed seat 71, a scraper 73 fixedly set on the rotating shaft 72 and located inside the feed pipe 2 for adhering to the surface of the grid 6, a connecting bevel gear 74 fixedly sleeved on the main shaft 42, and a transmission bevel gear 75 fixedly sleeved on the end of the rotating shaft 72 away from the scraper 73 and meshing with the connecting bevel gear 74. Multiple scrapers 73 are provided, and the multiple scrapers 73 are distributed in a ring on the rotating shaft 72.

[0041] When the main shaft 42 in the stirring mechanism 4 rotates under the drive of the motor 44, the connecting bevel gear 74, which is fixedly sleeved on the main shaft 42, will rotate synchronously with the main shaft 42. Since the connecting bevel gear 74 and the transmission bevel gear 75, which is fixedly sleeved on the end of the rotating shaft 72 away from the scraper 73, mesh with each other, the rotation of the connecting bevel gear 74 will drive the transmission bevel gear 75 to rotate, which will in turn drive the rotating shaft 72, which runs horizontally through the feed pipe 2 and the fixed seat 71 and is rotatably connected to both, to rotate. As the rotating shaft 72 rotates, the multiple scrapers 73, which are fixedly set on the rotating shaft 72 and located in the feed pipe 2 and are arranged in a ring, will rotate synchronously. Since the scrapers 73 are in contact with the surface of the grid 6, the rotating scrapers 73 can scrape off the raw material attached to the surface of the grid 6, preventing the raw material from clogging the grid 6. At the same time, the multiple scrapers 73 can also stir the raw material in the feed pipe 2 during the rotation process, preventing the raw material from accumulating in the feed pipe 2, thereby ensuring that the dust suction channel of the dust suction mechanism 5 is unobstructed and the feeding of the feed pipe 2 is smooth.

[0042] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
